PRINTING TABULATING MACHINE Filed Dec. 27 1924 19 Sheets-Sheet 19 Patented Nov.'"4,--1930 UNITED STATES PATENT OFFICE JOHN ROYDEN PEIRCE, OF NEW YORK, N. Y., ASSIGNOB TO INTERNATIONAL BUSINESS MACHINES CORPORATION, 01 NEW YORK, N. Y., A CORPORATION OF NEW YORK IPBIN TING .TABULATIN G MACHINE Application iiled December 27, 1924. Serial No. 758,850.

This invention relates to tabulating machines of the t pe wherein data are taken from perforated cards to control accumulating and printing operations of the machine.

The main object of the invention is to improve generally upon machines of this character; as for instance, by so constructing and arranging the parts and the mode of operation as to obtain greater operating speed and a higher degree of reliability than is at present possible. It is also aimed to increase the usefulness of this class of machines by producing a machine capable of a greater range of results.

Another object is to provide means whereby any one or more of the type bars may be controlled to suppress printing thereby without suppressing accumulating operations of the corresponding accumulator wheels.

Another object is to provide a machine wherein the printing of a character in a particular column will control the printing of zeros to the right of such column and also to provide means whereby a split may be effected at any point along the printing line beyond which such control shall not extend.

Anothenobject is to provide means whereby when atype bar which carries the accumulated racks rises beyond the 9 position, suppression of the carrying operation from the corresponding accumulator wheel to the wheel of the next higher order may be cf fected, so that the adding of 10 to any given accumulator wheel, besides placing such wheel in the position which it occupied before, will also leave the wheel of the next higher-order in its former position.- Other objects will appear in the following description of the invention.

Referring to the drawings wherein the preferred form of the invention is shown:

Fig. 1, is a view of the assembled machine. Fig. 2, is a plan view thereof.

Fig. 3, is a front sectional elevation taken on line 33 of Fig. 2, showing the card feeding and sensing mechanism.

Figs. 4 and 4,.taken together comprise a to section taken on line 4-4 of Fig. 2 showing the hand operating levers for controlling the operations of the machine proper.

Figs. 5 and 5 taken together comprise a section taken on line 55 of Fig. 2, showing cams and links controlled thereby for controlling the total taking operations of the machine.

Fig. 6 is the sectional elevation taken on line 6-6 of Fig. 2 showing'the printing being taken on line 10-1O of Fig. 6.

Fig. 12 is a section taken on line 1212 of Fig. 10 of a portion of the accumulator unit used in connection with group indicatlng.

Figs. 13 and 13 are sections of the mainportion of the accumulator unit taken on line 13-43 of Fig. 10 showing the parts in different positions.

Fig. 14 is an end view of the accumulator unit taken on line 1414 of Fig. 10.

' Fig. 15 is a detail of the accumulating and total-taking control mechanism.
